Résumé

The PRO.M.E.THE.O. study (PredictiOn Models in Ent cancer for anti-EGFR based THErapy Optimization) aimed to develop a predictive model (PM) of overall survival (OS) for patients with locally advanced oropharyngeal cancer (LAOC) treated with radiotherapy (RT) and cetuximab (Cet) from an Italian dataset. We enrolled patients with LAOC from 6 centres treated with RT-Cet. Clinical and treatment variables were collected. Patients were randomly divided into training (TS) (80%) and validation (VS) (20%) sets. A binary logistic regression model was used on the TS with stepwise feature selection and then on VS. Timepoints of 2, 3 and 5 years were considered. The area under the curve (AUC) of receiver operating characteristic of 2, 3 and 5 year and confusion matrix statistics at 5-threshold were used as performance criteria. Overall, 218 patients were enrolled and 174 (79.8%) were analysed. Age at diagnosis, gender, ECOG performance, clinical stage, dose to high-risk volume, overall treatment time and day of RT interruption were considered in the final PMs. The PMs were developed and represented by nomograms with AUC of 0.75, 0.73 and 0.73 for TS and 0.713, 0.713, 0.775 for VS at 2, 3 and 5 years, respectively. PRO.M.E.THE.O. allows the creation of a PM for OS in patients with LAOC treated with RT-Cet. Sviluppo di un modello predittivo in pazienti affetti da neoplasia dell’orofaringe: PRO.M.E.THE.O. L’obiettivo di PRO.M.E.THE.O. è quello di sviluppare modelli predittivi (MP) di sopravvivenza globale (OS) per pazienti (pz) con neoplasia orofaringea localmente avanzata (LAOC) sottoposti a radioterapia (RT) e Cetuximab (Cet), provenienti da un dataset italiano multicentrico. Sono stati arruolati pazienti con LAOC trattati con RT-Cet provenienti da 6 centri italiani, dei quali sono state raccolte variabili cliniche e di trattamento. I pazienti sono stati suddivisi casualmente in un training set (80%) e in un gruppo di controllo (20%). Per la creazione del MP è stata considerata l’OS a 2, 3 e 5 anni. L’area sottesa alla curva (AUC) di ROC (receiver operating characteristic) a 2, 3 e 5 anni e la statistica della matrice di confusione a 5 classi rappresentano i criteri di performance. 218 pazienti sono stati arruolati e 174 (79,8%) analizzati. I parametri testati per la costruzione degli MP includevano: età alla diagnosi, sesso, ECOG, stadio clinico, dose del volume ad alto rischio, tempo complessivo di trattamento e giorni di interruzione della RT. I MP di OS sono stati rappresentati con dei nomogrammi. PRO.M.E.THE.O. ha consentito la creazione di MP di OS in pazienti LAOC trattati con RT-Cet.
